S. Juen et al., SPECTRAL LUMINESCENCE ENHANCEMENT IN 3-DIMENSIONAL OPTICAL MICROCAVITIES FORMED BY GAAS MICROCRYSTALS, Solid-state electronics, 37(4-6), 1994, pp. 1163-1166
The photoluminescence of GaAs microcrystallites with average sizes in
the range of 0.35-1.3 mum has been studied experimentally. The observe
d spectral blue-shift and line-broadening of the luminescence are expl
ained by spectral enhancement and inhibition of spontaneous emission d
ue to a modified photonic density-of-states in the dielectrically conf
ined microcrystallites.
